Michael Ellerman c5e24354ef [PATCH] powerpc: Turn cpu_irq_down into kexec_cpu_down ... We currently have a ppc_md member called cpu_irq_down, which disables IRQs for the cpu in question. The only caller of cpu_irq_down is the kexec code. On pSeries we need to do more than just teardown IRQs at kexec time, so rename the ppc_md member to kexec_cpu_down and expand it. The pSeries code needs to know, and other platforms might too, whether we're doing a crash shutdown (ie. panicking) or a regular kexec, so add a flag for that. The pSeries implementation of kexec_cpu_down does an unregister VPA call, which tells the Hypervisor to stop writing stuff into our pacas. Without this we can get weird memory corruption bugs when we kexec, caused by the Hypervisor writing into the first kernel's pacas which happens to be somewhere interesting in the second kernel's memory.
